18 JavaScript Libraries You Should Know

JavaScript is one of the most popular and widely used languages. It is used everywhere, from front-end development to back-end development. It has a large community, and therefore, it has a lot of libraries and frameworks. These libraries make JS more powerful and easier. They save the developer from writing everything from scratch and thus save development and testing time. The code becomes reusable and more maintainable. JS provides a wide range of libraries for various purposes. In this article, we will talk about 18 JavaScript libraries that you should know. So, without further ado, let’s get started.

 

jQuery 

jQuery is a popular JavaScript library. It is fast, lightweight, and feature-rich. It allows us to write JS code in a much simpler and quicker way. A functionality that takes many code lines in JS can get implemented using jQuery in only 1-2 code lines. With jQuery, DOM manipulation, AJAX calls, event handling, and animations become a breeze. It also has cross-browser compatibility. Therefore, the code written can run seamlessly across most browsers. Moreover, it reduces the complexity through abstraction, i.e., you only have to call the method and do not need to know how it works. 

 

D3.js 

D3 stands for data-driven documents. It is an open-source library that does efficient manipulation of documents depending upon the data. For example, if you have data stored in an array, you can use D3.js to visualize it using HTML, SVG, or CSS. It works with web standards such as HTML, SVG, and CSS. Therefore, you don’t need to learn anything new, and it has extraordinary flexibility.

It also provides an easy selection of DOM elements by using a declarative approach. After that, you can perform any manipulation and styling on them.

D3 is very fast with minimal overhead. It supports large datasets and code reusability.

 

Anime.js

Animations have now become an essential part of any website. They make your website interactive and engaging. Anime.js is a lightweight JS animation library that allows you to add cool animations to your website. You can set animations on anything such as SVG, CSS, HTML, DOM, and JS objects. Its powerful API helps you to add complex animations easily. With anime.js, you can animate various CSS transform properties with different timings simultaneously on an HTML element. It also provides many callbacks and control functions to play, control, pause, and trigger events.

 

Parsely

Parsely is a JavaScript library that performs front-end form validation. It is quite a simple and user-friendly library. You can easily add validation information inside HTML tags without writing any JS code and Parsely takes care of everything else. It provides you many useful built-in validators, but you can also craft your own according to your requirements. Parsely also performs dynamic form validation. It can automatically identify modifications to the form data and then transform its validators. Parsely is UI and UX focused, and thus, it allows you to customize its default behavior according to your requirements. Moreover, it is open-source, bug–free, and rigorously tested.

 

Socket.IO

Socket.IO is another popular and powerful JavaScript library for real-time web applications. It enables real-time, two-way event-based communication between the browser and the server. Moreover, it consists of a node.js server and a JS client library for the browser. Socket.IO is reliable, efficient, and works on most platforms such as browsers and mobiles. With Socket.IO, you can create apps with real-time analytics, instant messaging, binary streaming, and document collaboration. It provides features such as automatic reconnection, packet buffering, and room (broadcasting to all or a part of clients).

 

React

React is an open-source JavaScript library that allows us to create single-page web applications. It focuses on the UI part of an application and is based on the Model View Controller (MVC) architecture. React.js follows the component-based architecture, and thus, the application gets divided into small independent parts, which get combined to create a more complex UI. Since it uses components, the code becomes more reusable, maintainable, and optimizable. It works on virtual DOM, and thus, it is efficient. Moreover, it is developed and maintained by Facebook and has quite a large community and support.

 

Google Polymer

Polymer is a JavaScript library that allows you to create websites using web components. It is an open-source library created at Google. With Polymer, you can reuse HTML elements. You can also create your custom elements with HTML, CSS, and JavaScript. It provides cross-browser compatibility and works in almost all browsers. Moreover, it provides one-way and two-way binding. 

 

Glimmer

Glimmer.js is another popular open-source JavaScript library that is used to build UI components for the web. It provides functionalities to define, create and render components. Moreover, it keeps the DOM in sync with the internal state of the component. Components provided by Glimmer are fast and lightweight. It is built on top of the Glimmer VM, a rendering engine of Ember.js.

 

Three.js

Three.js is a JavaScript library API that allows you to create and display animated 3D computer graphics easily. It provides great performance and makes WebGL easier. WebGL is an API that helps you to access the computer graphics hardware (to draw 3D objects) using JavaScript and renders the result in a typical canvas element. With three.js, you can create or delete objects during runtime. It allows you to add various features such as a camera, lights, and animations. Moreover, it has good documentation available with examples. It also has a large community, and thus, a lot of third-party plugins are available.

 

Bideo.js

If you want to add background videos to your web page, then bideo.js is the library you are looking for. It makes the task of adding videos a breeze. You can add a video as a background of the complete body or some container. The video element used adjusts to its container dimensions automatically and resizes when the browser's window does. It also provides auto-play, high-resolution playback, and scales super easily.

 

JavaScript is used in various places, and thus, it provides libraries for different purposes. The above-given libraries were some of the top libraries that are commonly used. However, there are many other libraries and frameworks that you can use depending upon your use case to make your task simpler and efficient.

 

Lodash

When it comes to JavaScript development, you will always be needing utility functions to accelerate the development process. Lodash has all the utility functions that are needed for day-to-day programming tasks. Behind the scene, Lodash is based on Underscore.js which is also an amazing library. This library makes your code a lot cleaner and easier. In Lodash, you have methods to iterate objects, strings, arrays, creating composite functions, and much more.

 

Chalk

Console.log() is the most widely used technique for debugging your program. From beginners to experienced developers, all rely on Chalk in making their web apps better. Chalk provides a colorful representation for your console output without compromising any of the performance. There are 256 colors currently supported along with the style nesting. If you are tired of the boring console, chalk is waiting for you.

 

Commander

When it comes to backend development, the command line interface is the center of it. As JavaScript does not have its own command-line interface, Commander is an amazing library that provides an interface for the server-side JavaScript. It comes with features like asynchronous support, custom event listeners, custom help, and much more. 

 

Request.JS

When it comes to the application layer, HTTP is the most commonly used protocol. Any frontend developer will always need an HTTP client. This is where Request.JS comes into play. Request.JS is the most popular HTTP client with tons of advanced features. Request is simple yet powerful as it offers features like HTTP authentication, Custom HTTP headers, OAuth signing along with SSL support. 

 

Express.JS

For using Javascript for the backend, you will be needing to implement the HTTP server and Express.JS is the best solution for it. It is a lightweight solution for server-side Javascript and it is mainly used to develop high-performing web applications and REST APIs. Express.JS is the foundation for many other JavaScript Web Frameworks. It supports middlewares, routing, server-side template engines, caching, and much more. 

 

Moment.JS

As a web developer, dealing with date and time is a common task and sometimes, it becomes a huge headache. In the earlier versions of JavaScript, there was not much support for date and time manipulation which led to the release of Moment.JS and since then, it has become a standard way of dealing with date and time. 

 

FS-extra

In the backend JavaScript, dealing with the file system is a common routine. Sadly, NodeJS offers very little functionality when it comes to file systems. To fill this void, FS-extra offers additional advanced functionality to deal with the file systems. From preventing EMFILE error to drop-in placement for the filesystem, FS-extra covers everything. 

 

Popper.JS

This library helps you create poppers for your websites. As creating and positioning poppers is a headache in Vanilla CSS and JavaScript, this library adds a lot of abstraction; making things easy.  There are tons of variations for the element poppers in this library. The best thing about Popper.JS is its lightweight and has no dependencies.
